fruit fly (forum)

yry starts with ...
Does anyone have information on how far a fruit fly can fly? This becomes important if you have neighbours that neglect control. I suspect they can travel several kilometres.

last I read, 10 to 20 km is the estimated range. I recall this number from either DPI (Qld) or the NSW equivalent. They were trying to build a fruit fly 'barrier' and have like a 20 km exclusion belt.

You only know if the trap really works if you can positively identify there are females inside!

Has anyone tried the mesh bags from Greenharvest to protect Pink Lady apples from fruit fly.They completely enclose the fruit and are too finely meshed for the fly to penetrate.I live in Parramatta and this is the first fruit for 6 years after I planted a Granny Smith companion tree last year.

Ivepeters, i live in Tingalpa.

Granger, i havent used the sleeves from greenharvest but i found the Fruit Protection Bags are only held on the branch by a thin wire which blows off easily in strong winds and doesnt let the air pass through like with organza bags.

If you haven't seen it yet, check out Daley's blog page. Look at the October issue of the Bundaberg Rare fruit online articles. There's an interesting solution to fruit fly one of the growers swears by. (Other good reads to be had too.)

Not new. It is the principal behind Amulet , a commercial f.fly bait that has a 60per cent kill rate. Useful but not a big deal . Incidentally Fipronil is v. expensive.

It is the flies that die 2 days later after coming in contact and spreading the poison to the females where this may have longer term potential in reducing numbers. Not reliable as the sole method for one season.

Yes, in this case it is an STD of fruit flies.

Ivepeters,I use the mesh bags which have string attached to the base which enables you to firmly tie the bag to the trunk.The fine mesh keeps the flies out but allows air to flow through.

They have finally arrived at my place.
I use organza bags mostly, also a couple of cera traps.
Just got some eco-naturalure to try out this season as well.

If you caught 30 males in an hour you have no control at all. Male traps are purely for estimating need for other measures.

I have lures for the males plus traps and foliar spray which kills both. I am sure there are some females in there also by now besides the more males you take out of the cycle the better.

The lure with the wicks are really just a monitoring tool to determine f.fly pressure.
I would say your foliar spray probably does more to control even though you don't see the results.

I suppose what you call foliar spray is what others call cover spray. The latest Plant Protection Guide of NSW Primary Industry only allows Malathion as a cover spray and that is only a temporary registration. I think people will need to familiarize themselves with yeast autolysate baits (Natflav or Pinnacle).

I discovered a possum had eaten one of my Anna apples today, and through the fruit fly bag protecting it. So rude!
